- Q: Are steel coils affected by magnetic fields?
- Yes, steel coils can be affected by magnetic fields. Steel is a ferromagnetic material, which means it can be magnetized or attracted to magnets. When a magnetic field is applied to a steel coil, it can induce a magnetic field within the coil, causing the coil to become magnetized. This can have several effects depending on the strength and duration of the magnetic field. If the magnetic field is strong and the coil is exposed to it for a significant amount of time, it can cause the steel coil to retain some magnetism even after the magnetic field is removed. This can be problematic in certain applications where a non-magnetic material is required, as the magnetized steel coil may attract or interfere with other nearby objects. On the other hand, if the magnetic field is rapidly changing or fluctuating, it can induce electrical currents within the steel coil through electromagnetic induction. These induced currents, known as eddy currents, can generate heat within the coil, leading to energy losses and potential damage to the coil. Therefore, it is important to consider the effects of magnetic fields on steel coils in various applications. Protective measures such as shielding or demagnetizing processes may be necessary to minimize the impact of magnetic fields on steel coils when required.
- Q: I am in the US and looking for a price on wide flange steel. I need a price of one W10x30 and 20 feet long.
- The price of steel is increasing daily, so an exact answer is rough. A W10x30 is a fairly common shape and shouldn't be too hard to find. For a very rough ballpark number, say $700/ton (installed price), the piece you require should be in the range of about $250.00 or less as I assume you'll be doing the installing. Please don't take this as the gospel, however. Price varies on location, stock, and availability. Open the phone book and contact your local steel supplier. Because the piece you require is fairly short, you might get lucky and find someone who has a waste piece that length that they will give you a good deal on. --------------------------------------... I just checked the AISC web site to verify the number I quoted above and they posted an article stating that the average mill price had just increased to over $1000/ton in May. The best advice I can provide at this point is to buy the W10 now and don't wait any longer.
- Q: What are the common surface defects found in steel coils?
- There are several common surface defects that can be found in steel coils. One of the most common defects is rust or corrosion. This occurs when moisture comes into contact with the steel surface, causing it to oxidize and form rust. Another common defect is scratches or abrasions, which can occur during the handling or transportation of the coils. These can range from minor surface scratches to deeper gouges that can affect the structural integrity of the steel. In addition, there can be surface roughness or unevenness, which can be caused by improper rolling or cooling processes during manufacturing. This can result in an inconsistent surface texture that may impact the appearance and performance of the steel. Another defect is scale, which is a layer of oxide that forms on the surface of the steel during the manufacturing process. This can give the steel a rough and uneven appearance. Finally, there can be oil or grease stains on the surface of the steel, which can occur during the manufacturing or handling process. These stains can affect the adhesion of paints or coatings applied to the steel. Overall, these common surface defects in steel coils can impact the quality, appearance, and performance of the steel, and may require remedial actions such as cleaning, grinding, or recoating to resolve.
- Q: I am making a sword of 1060 carbon steel and would like to know how to heat treat it once it's ready, could anyone help please?
- Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
- Q: I bought a Remington 870 super mag last fall and wanted to to switch to non-tox steel loads. The gun came with a modified rem choke. I know that not all chokes are qualified to handle steel. It doesn't say anywhere on the choke no steel I was just wondering if anyone out there knew for sure that those chokes that the guns come with won't get damaged be steel.

- Q: What is the purpose of coating steel coils?
- The purpose of coating steel coils is to provide protection against corrosion, enhance durability, and improve the aesthetic appearance of the steel. Coatings create a barrier between the steel surface and the environment, preventing moisture, chemicals, and other corrosive elements from reaching the metal. Additionally, coatings can offer additional benefits such as heat resistance, UV protection, and improved paint adhesion, making the steel coils suitable for a wide range of applications in various industries.
- Q: What are the dimensions of steel coils used in the oil and gas industry?
- The dimensions of steel coils in the oil and gas industry can differ based on the specific application and needs. Nevertheless, there are commonly used dimensions. Steel coils in the oil and gas industry typically possess a width that ranges from 600mm to 2000mm. The coil's outer diameter can vary from 800mm to 2200mm, while the inner diameter can range from 508mm to 610mm. The coil's weight can also vary, ranging from a few tons to several tens of tons. These dimensions are tailored to fulfill the requirements of diverse processes in the oil and gas industry, including pipe manufacturing, storage tank fabrication, and offshore platform construction. It is important to emphasize that these dimensions are not fixed and can be customized to meet the specific demands of each project.
- Q: i like stainless steel guns, especially the SW 686 .357, i plan on getting one but my question is would polishing the stainless steel make the gun more prone to corrosion over leaving it as it is? and will the polished surface appear uneven after use and sitting? obviously all metal takes some sort of upkeep but is polished more high maintenance than non-polished?

- Q: How are steel coils inspected for flatness using optical sensors?
- Steel coils are inspected for flatness using optical sensors by employing a system known as optical flatness measurement. This method involves the use of high-resolution cameras that capture images of the steel surface as it passes through the inspection line. Firstly, the steel coil is unwound and passed over a roller table. As it moves, the optical sensors are positioned above the coil to capture images at regular intervals. These sensors typically consist of a combination of laser line projectors and high-resolution cameras. The laser line projectors emit a thin, straight line of laser light across the width of the steel coil. This laser line acts as a reference plane for measuring the flatness of the steel surface. The high-resolution cameras then capture images of the laser line as it interacts with the steel coil. The captured images are then analyzed using advanced image processing algorithms. The algorithms analyze the deformation of the laser line on the steel surface and calculate the deviations from the flat reference plane. These deviations indicate any irregularities or variations in the flatness of the steel coil. The optical sensors can accurately detect even the slightest deviations in flatness, measuring them in micrometers or even smaller units. This enables manufacturers to identify and rectify any flatness issues in the steel coils before further processing or shipment. In addition to measuring flatness, optical sensors can also detect other surface defects such as waviness, scratches, or dents. By incorporating multiple cameras and laser line projectors from different angles, a comprehensive inspection of the steel coil's surface can be achieved. Overall, the use of optical sensors for inspecting steel coil flatness provides a fast, accurate, and non-contact method. By detecting and rectifying any flatness issues early in the production process, manufacturers can ensure the delivery of high-quality steel products to their customers.
- Q: What are the common coil storage conditions?
- The common coil storage conditions include keeping the coils in a dry and well-ventilated area, away from direct sunlight and extreme temperatures. It is also important to store the coils in an upright position, on pallets or racks, to prevent damage and ensure easy access for handling and transportation.
